It is always possible to pray: the time of the Christian is that of the risen Christ who is with us always, no matter what tempests may arise. Our time is in the hands of God:
It is possible to offer fervent prayer even while walking in public or strolling alone, or seated in your shop, . . . While buying or selling, . . . Or even while cooking.
